taking video and pics at a concert

[xxxjdoggxxx]

I am going to a Slipknot concert on Tuesday and was wondering if anyone has any tips on getting good video clips and pics with the touch pro. Is there any apps that may help me out? I'm not trying to get a video of the whole thing (i doubt the battery would last that long) just maybe a song or two and some pics. The phone I had when I went to the last concert I went to is a Moto KRZR so the Pro should do way better than that. Also is a 1gb memory card going to be enough or should I get something bigger?
